【求教高手】：有关DataGrid的问题

[Qinglei]

我自己手动写了一个dataTable实现与datagrid的绑定，但是在datatable添加一行时，报告说“产生的行中没有某个列，这是怎么回事情，我每次都实现了datagrid的重新绑定

代码看看

产生的行中没有某个列

编译器不是告诉你了吗？

for( int i=1;i<=5;i++)
{
DataRow myDataRow = contentTable.NewRow();
myDataRow["yeWuType"]="";
myDataRow["dianLuType"]="";
myDataRow["dianLuAttri"]="";
myDataRow["dianLuSpeed"]="";
myDataRow["hireAmount"]="0";
myDataRow["monthRate"] ="0";
myDataRow["favourRate"]="";
myDataRow["yearRate"]="0";
myDataRow["startTime"]="";
contentTable.Rows.Add(myDataRow);
}
}
dataView = new DataView(contentTable);
editDataGrid.DataSource = dataView;
editDataGrid.DataBind();
lastEditPage = editDataGrid.CurrentPageIndex;

增加行
if( addRowCount.Text.Trim()!="")
{
int addRowNum = Convert.ToInt32( addRowCount.Text);
for( int i=0;i<addRowNum;i++)
{
DataRow row = contentTable.NewRow();
row["yeWuType"]="";
row["dianLuType"]="";
row["dianLuAttri"]="";
row["dianLuSpeed"]="";
row["hireAmount"]="0";
row["monthRate"] ="0";
row["favourRate"]="";
row["yearRate"]="0";
row["startTime"]="";
contentTable.Rows.Add(row);

}
}
DataGridDataBind();

[Qinglei]

row["yeWuType"]="";运行时报告出错,说yeWuType不是表中的行

[tavor]

it means some column(which can't be null) of your new row has no value,you should write code like this:

DataRow dr=new myDataTable.NewRow();
dr[0]=youvalue1;
dr[1]=youvalue2;
......
dr[n]=youvalue3;

myDataTable.Rows.Add(dr);

then you can bind yourtable to your grid.

你得用0,1.2.3.4....来表示
